Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention has a tub which sprays liquid onto a dish by means of a circulation pump and at least one rotating washing arm and collects at the bottom of the tub, from which it is distributed to wastewater etc. by means of a drainage pump. The present invention also relates to a trash-crushing device for a dishwasher, in which a collecting means for collecting trash from the dish is provided at the bottom of the tub.

[0002]

2. Description of the Prior Art Devices of the above type are known in the prior art, the bottom of the tub being provided with one or several sieving members which normally cover the drainage water, after which water is collected and then circulated by a circulation pump. It is circulated to the washing arm inside. After each wash cycle, the water is drained from the sump with a drainage pump.
Usually, the sieving member will carry the debris that has fallen from the pan to the sieving member due to the water stream to a certain location on the sieving member, which is a removable basket or a relatively easily accessible basket or similar for cleaning. Is formed as a thing. However, cleaning often has to be done manually with running water.

In order to reduce the work of cleaning the sieving member for separating the litter from the liquid, it is arranged in the circulation system of the dishwasher (DE 1129667 and EP 797).
It has also been proposed in the past to crush waste by passing it through a rotary cutting element (see DE 1144447) or connected to a drainage pump. Relatively large bones, debris, etc. are removed by the coarse sieving element in front of the cutting element.

However, when using these devices, there is a risk that a hard object will follow the water and clog the cutting element and the pump, since the cutting element is integral with the blade or its drive. Removing such hard objects is cumbersome and time consuming. That is, the cutting element can only be touched after disassembling most of the machine.

It is also known in the prior art to clean the collecting part of the sieving member by spraying water from one of the washing arms onto the collecting part of the sieving member, crushing the material and removing it with the wastewater (EP 150478). No.). However, this method also has some drawbacks. That is, since the water pressure is not particularly high, it can only be used for a material that is soft and can be easily divided.
Also, functionality is limited to an annular surface that is much smaller than the bottom surface of a basket-type collection container. As for the structure, there is a drawback that the amount of water required for washing dishes is large, which is negative from the viewpoint of energy consumption. Another disadvantage is that it is necessary to maintain the liquid level for debris at a special level above the inlet opening of the circulation pump and below the surface of the filter. For example, if the nozzle of the cleaning arm is clogged, there is a risk that the surface of water for dust will rise and the jet of water from the cleaning arm will impact the surface of the water rather than the dust.

SUMMARY OF THE INVENTION It is an object of the present invention to effectively crush trash by means separated from the pumping action, to separate relatively large particles of crushed trash from circulating water, and to drain during dishwashing. The purpose of the present invention is to provide a device that stores the water at the inlet side of the pump and discharges it together with sewage. Also, the structure is very convenient for the user because it can be contacted very easily and can be easily disassembled. Yet another advantage resides in the effective mechanical cleaning of the filter area, which is part of the dishwasher's separation system.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the drawing, 10 is a dishwasher tab, and the dish is placed in a bracket not shown. tab
Within the housing 10 one or several rotary cleaning arms 11 are provided, from which liquid, preferably water, is sprayed via a nozzle 12 onto a dish. The bottom 13 of the tab 10 is inclined towards the refuse debris 14 and is covered by a hopper-shaped fine sieving member 15. For garbage
14 has an outlet opening 16 in the lower part of the side wall,
16 communicates with a circulation pump 17, the outlet of which is connected via a hose 18 to a pipe 19 arranged in the center of the tub 10, on which the rotary cleaning arm 11 can rotate. It is supported. The litter bin 14 has another outlet opening 20 at its bottom, which is connected to a drainage pump 21 by means of which a water in the dishwasher is connected to a sewer (not shown) by a hose 22. Exhausted through.

A vertical shaft 23 is provided inside the refuse debris
The vertical shaft 23 is driven by a motor 24 fixed to the underside of the bottom of the refuse debris 14 and is sealed from the debris by a sealing member 25. The vertical shaft 23 supports a cylindrical brush holder 26, and the cylindrical brush holder 26
Is provided with bristle elements 27, which form a cleaning device which follows the rotation of the shaft, on two mother surfaces located opposite one another. The tips of these bristle elements 27 contact a sleeve 28, the enclosing surface 29 of which comprises a fine sieving element, for example a wire mesh, which is fixed between an upper ring 30 and a lower ring 31. Between the upper ring 30 and the lower ring 31, there are several ribs 32 circumferentially equidistantly acting as brush cleaning elements. The lower ring 31 of the sleeve 28 is located on an inwardly facing flange 33 below the water guiding member 34 located at the bottom for the refuse. The outwardly directed flange 35 of the water guide member 34 is oval and abuts a side wall for the debris near the inlet of the circulation pump, while the opposite flange is located at a distance from the side wall. , Is fixed to the side wall by two separating means 36. The cylindrical wall 37 of the water guiding member 34 has an opening 38 in its lower portion.
Water through this opening 38 between the two annular spaces 39, 40 formed between the sleeve 28 and the water guide member 34 and between the water guide member 34 and the wall of the refuse debris 14. Can flow freely.

The upper ring 30 of the sleeve 28 carries a cup-shaped hat 41, which is provided in the center with a rough grid 42 forming the collecting means and forming a container 43.
The container 43 is covered by the grid 42 and is surrounded by an enclosing surface or sleeve 28 and the bottom of the litter debris 14.

Above the grid 42, the vertical shaft 23 is provided with a plurality of blades 44 forming cutting means. These blades 44
Is curved, and is adapted to cooperate with the lattice 42 to crush the objects falling there. The blade 44 is attached to the blade support arm 45, which is fixed to the vertical axis 23 with a nut 46, which is removably tightened to allow the blade 44 to be removed and the device to be disassembled. ..

The operation of the device is as follows. The food residues and debris that fall from the plate to the bottom of the tub are carried by the water stream towards the grate 42 to a fine sieving member where they are parked. At some scheduled time, the motor 24 will start and rotate the vertical shaft 23 and the blade 44. Thereby the grid
The trash on 42 is crushed and transferred to container 43.
All relatively large lumps remain in the container during water circulation, but are discharged into the sewage when the drainage pump 21 is started. Simultaneously with the cutting of debris by the blade 44, the inside of the enveloping surface 29 is cleaned by the bristle elements 27 in contact with the fine sieving member. As the bristle elements 27 pass through the ribs 32, the bristle elements 27 vibrate and the lumps that collect in the bristles 27 fall to the bottom for debris and are discharged with the sewage. It should be mentioned that the motor 24 is only activated temporarily, for example for a short time, and in the first stage of the dishwashing operation the motor is driven at a relatively low speed.
